On Saturday's Smerconish show on CNN, host Michael Smerconish brought aboard Democratic activist and media darling from the 2016 presidential campaign, Khizr Khan, and gave him an unchallenged forum to hint that the U.S. has helped create immigrants who are fleeing wars and climate change. He also tied defeating President Donald Trump in 2020 to thwarting the kind of white nationalism that led to the recent terrorist attack on a mosque in New Zealand.
